GUARD. FORI INVERTEI) INCANDESCENT MANTLES.

Specification of Letters Patent.

Application led February 10, 1911. Serial No. 607,763.

To all whom t may concern Be it known that I, THOMAS J. LITLE, J r., aresident of "Woodbury, Gloucester county, State of 'N ew Jersey, haveinvented a new and useful Improvement in Guards for InvertedIncandescent Mantles, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure l is a sectional sideelevation, showing a mantle provided with my improved guard in acylindrical box; Fig. 2 is a side elevation of the mantle taken at rightangles to that of Fig. l; Fig. 3 is a top plan view of the same in thepacking box; and Figs. 4 and 5 are sectional views at right angles toeach other showing the mantle in a square packing box.

My invention relates to mantles for inverted incandescent gas lamps, andis designed to provide a simple and eflicient guard therefor which willprotect the mantle both in shipping and handling, andv will also providea handle by which the mantle may be applied and removed without dangerof injury thereto.

In the drawings, 2 represents the mantle which may be of the ordinaryform for inverted incandescent lamps, its open end beingsecured to theusual refract-ory ring 3, having the integral radial legs or prongs 4.These prongs are usually spaced equidistantly about the ring. To theprojecting portions of two of these ring legs, I secure the ends of theloop-shaped wire'guard 5, preferably by bending these ends about thelegs, and if desired, cementing the hook portions 6 in place. The legsmaybe and preferably are grooved to receive these wire hooks. From thehook portion, the wire is bent sidewise so asl to bring the opposite armportions 5, 5 of the wire at diametrically opposite sides of the mantle.The intermediate portion 7 of the wire is preferably bent into the formof a project-ing handle by which the mantle may be inserted in the box,applied, etc.

Then the mantle is taken by the guard handle 7 and slipped into acylindrical pasteboard box, such as shown as 8 in Figs. l and 2, thewire will contact with the sides of the box and frictionally hold themantle in place, together with the refractory prongs or legs 4, whichalso preferably engage the y sides of the box.

guard are spaced apart from the mantle to about the same distance as theedges of the legs 4, so as to firmly hold the mantle in place in thebox. The guarded mantle may also be shipped in asquare or angular box,such as shown at 9 in Figs. 4 and 5,this box having a metallic clip 10,secured to an inner end wall. This clip is arranged to receive theinwardly projecting portions of two of the legs, the clip having a lugportion 11 which may be bent up against the end of the third leg on theopen side of the box, thus holding it in place. The wire guard does n-otinterfere with this clip holding in the square box, but assists inguarding and holding the mantle in place in suchv box. This square boxhas a removable cover 12, .the two members telescoping sidewise overeach other.

The advantages of my invention result from the simplicity andeectiveness of the guard which may be easily bent up out of wire orsimilar material and attachedl to the legs or prongs of the base ring.The guard protects the mantle during` handling and is easily and cheaplyapplied to the existing forms of rings. The handle also provides foreasy handling of the mantle without danger of the fingers touching themantle and injuring it.

Changes may be made in the form and arrangement of the wire, the mantle,etc., without departing from my invention.

I claim:

1. A mantle guard for inverted incandescent mantles formed from a singlepiece of wire having two vertically extending arms, and a hook member atthe upper end of each of said arms, said hook member being arranged toengage the tops and bottoms of two of the projections on themantlesupporting ring; substantially as described.

2. An incandescent mantle secured to a supporting ring, radiallyextending supporting legs on the mantle ring, a mantle guard formed froma single piece of wire having vertical legs on opposite sides 4of themantle, and a hook member at the upper end of each of said arms eachengaging the top and bottom of one of the legs on the mantle-supportingring; substantially as described.

3. An inverted incandescent mantle secured to a supporting ring,radially extending legs on the mantle rin-g, a mantle guard PatentedApr. 8`, 1913. y
